The invention discloses a self-priming vortex pump, which comprises a fixed base and a water pump. The left and right sides of the bottom of the fixed base are provided with inner grooves, and the inside of the inner groove is provided with a pneumatic cylinder, an air pressure push rod, a bearing and Moving mechanism, the upper left of the fixed base is provided with a guide post, a guide post groove, a damping spring and a damping plate, and the top of the damping plate is fixedly connected to a water pump motor, and the water pump motor is located inside the soundproof cover. The sound insulation cover is fixedly connected to the shock absorbing plate, and the lower left side of the sound insulation cover is fixedly connected with a cooling fan. When the water pump needs to move, through the design of the air pressure push rod and the moving mechanism, the base can be effectively raised to allow the moving mechanism to contact the ground, so as to achieve the effect of moving the water pump, reduce the labor intensity of the workers moving the water pump, and improve the efficiency of the water pump. When a good location is selected, the moving mechanism is hidden in the inner tank through the pneumatic telescopic rod, allowing the inner tank to touch the ground, which improves the stability of the pump.
